SUPERNOVA 2009bv IN IC 4199
     P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports that a spectrum (range 360-800 nm) of
2009bv (cf. CBET 1741), obtained on Mar. 27 UT by M. Calkins with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia
supernova.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) indicates that 2009bv is a type-Ia event about one week before maximum
brightness.
